Too ll whom it may concern:

' Be it known that I, EDWARD T. Bunnowns, Y

' a citizen of the United States, residing at Portland, in the county of Cumberland and State of Maine, have invented certain new and useful Improvements in Holding Means for Roller-Screens, of which the following is a specification.

This invention relates to window'screens, and more articularly to screens of the rollcurely holding the lower end of the screen in posit1on.

Still another proved means for holding the edges of the screen in contact with the window frame. In order that the invention may be readily understood, reference is had to the accom-' panying drawings, forming part of this in Fig. 1; Fig.

specification, and in which,

Figure 1 is a fragmentary vertical section through a window, showing my improved screen applied thereto; Fig. 2 is a similar view showing a slightly modified construction; Fig. 3 is a fragmentary front elevation of the screen construction shown in Fig. 1, parts being in section; Fig. 4 is a fragmentary front elevation of the screen supporting means shown in Fi 2; Fig. 5 is a perspective view of one o the brackets employed in the arrangement shown 6 is a fragmentary longitudinal section of one of the bars, showin the screen material wound thereon; Fig. is a side elevation of a slightly different form of bracket which I may employ; Fig. 8 is a side elevation of the improved bracket shown in Figs. 2 and 4, the screen and bars being shown as held in stored position therein; Figs. 9, 10, and 11 are horizontal fragmentary sections on an enlarged scale, showing difi'erent forms of spring clips or clasps which I may employ to hold the free edges of the screen;Fig. 12 is a perspective view of the preferred form of such clasp, as shown in Fig. 11; Fig. 13 is a horizontal section through the clasp shown in Fig. 12;

and, Fig. 14 is a fragmentary perspective view showing a different form of bar.

Referring to the drawings in detail, 1 indicates the window frame, 2 the inner guide strip, 3 the partition strip or bead,

.and 1 the blind stop, as in the above mentioned applications.

' 5 indicates the window sill, and 6 and 7 the upper and lower sashes, respectively, while the runway for the upper sash is indicated at 8.

As in my former constructions, the screen itself consists of a piece of flexible netting material 9, secured at its ends to a pair of bars or rollers 10 and 10, on eitheror both of which the material may be. wound. As clearly shown in Fig. 6, this material does not extend entirely to the end of the bars, such as 10*, but a short length of the bar is left profecting beyond the material at each.

end, as indicated at 10 in Fig. 6.

In order to support the bars in position, I provide, in this instance, spring brackets or hangers 11, as shown in Fig. 1, such hangers being mounted upon the upper sash of the window, one at each side. By reference to F ig. 5, it will be seen that each hanger or bracket 11 comprises curved portions or loops 11 and 11", adapted to receive the ends of, the bars 10 and 10*, respectively, such loops being connected by a bent portion 11. At the upper end of the loop 11 is provided a flat portion 11,preferably having a hole through which a nail or screw may be driven into the lower edge of the upper sash, as clearly shown in the drawings. It will be understood that these brackets are made of an extremely thin and relatively narrow resilient strip, and are disposed at each side of the window in the runway 8.

It will be understood that when the screen is in operative position, as shown in Fig. 1, the loop 11 is idle, but that this loop serves to support the end of the bar 10 when the screen is in rolled up or in-operative position for storing. In some cases, it may be found desirable to employ in connection with such a bracket, a locking bar, as illustrated at 22in Fig. 7, to retain the rollers in position, such bar being pivoted at 23 to the upper end of the bracket 11' and adapted to engage the lower end 24 thereof, as will be understood.

In order to. securely hold the free edges of the screen, I preferably employ a spring Q eiiaoe clip or clasp of the character illustrated in Figs. 9, '10, or 11. By reference to Figs. 9 .and 10, it will be seen that the clip or clasp 15 or 15 comprises arms extending at right angles to each other, one of said arms being clamped between the auxiliary strip 13 secured to the blind stop 4, and the other of said arms being slightly spaced from and extending parallel with the side of said strip. The edge of the screen material is clamped between the clasp and strip.

While in Figs. 9 and 10, I have illustrated a one-piece clip, in Figs. 11, 12, and 13, I have shown a clip formed oftwo arms 16 and 17, pivoted together at 18. The portion 17 is held between the strip 13 and blind stop 4, while the arm 16 is free to swing about the pivot 18 to the position shown in dotted lines in Fig. 11. Spring means is provided for resiliently urging the arm 16 toward its normal or full line position. This may be accomplished by the construction shown in Figs. 12 and 13. By reference to such figures, it will be seen that the arm 16 has a spring tongue 19, formed integral therewith, the free end of which rests against a shoulder 21 formed by cutting away a portion of that part of the arm 17 which is bent around the pin 18, as indicated at 20. It will be apparent that any movement of the arm 16 about the pivot 18 will be resisted by the free end of the spring 19 bearing against the shoulder 21, and that this resilient pressure will cause the arm 16 to snap back into full line position and thus clasp the screen material between itself and the strip 13. It will be understood that a plurality of these clips or clasps may be employed, as shown in Figs. 1 and 2, and that when the screen is to be inserted in the window, the arms 16 are first swung back to dotted line position, and then, after the screen has been placed in position, thrown down so as to grip the edge of the screen, as will be obvious.

In order to hold the lower bar infirm contact with the sill and blind stops, I provide a spring clip 14, preferably secured to the sill at each side of the window, as shown in Figs. 1 and 3. The ends of the bar 1O are resiliently and frictionally held between this clip and the blind stop.

Instead of the hanger shown in Figs. 1, 3, and 5, I may, in some cases, employ the spring bracket illustrated in Figs. 2, 4, and 8. Such bracket is designated in its entirety by the reference character 25, and is generally of inverted U-shape, having a flat portion 25, adapted to be secured to the bottom edge of the upper sash 6. Each of these brackets comprises upper and .lower curved portions or sockets 25 and 25, adapted to receive the bars 10 and 10*, respectively, such sockets being separated by the restricted portion, and the lower ends of the bracket being flared outwardly so that the bars may be jed up into position-in the brackets.

Instead, of employing only two brackets,

as illustrated in Fig. 3, I may, in some cases,

mount screen rollers upon the upper sash I and to such I make no claim in this application. It will be noted, however, that in the present invention, no pintles or pivots are provided for the rollers, but that the ends of the rollers themselves are frictionally gripped by the resilient brackets.

While I have shown and described the elements 10 and 10 as rollers, it will, of course, be obvious that they are not necessarily round, but may be oflixagonal, octagonal, or other shape. An octagonal bar is illustrated by Way of example in Fig. 14.

Instead of the resilient clip-14 shown in Fig. 1, adapted to grip the lower bar between itself and' the blind stop, a holding clip of hook form may be employed, as indicated at 26 in Fig. 2.

What I claim is: 1. The combination with a window having the usual upper sash,.of a screen for such window, said screen comprising a rigid transversely extending bar, and hangers carried by the lower edge of said sash in which said bar is supported and held against rotation, said hangers embracing the sides of said bar at each end thereof and being so shaped that the bar may be moved laterally into and out of position therein.

2. The combination with a window having the usual upper sash, of a screen for such window, said screen comprising a rigid transversely extending bar, and laterally opening resilient brackets carried by and depending from the bottom of said sash in which the end portions of said bar rest, said brackets frictionally embracing)said bar and permitting its disengagement y a horizontal movement.

3. The combination with a window having the usual upper sash, of a screen for such window comprising a piece of flexible ma terial, upper and lower bars to which such material is secured, and on'which it may be wound, and a pair of brackets carried by said sash, said brackets being shaped to embrace the end portions of both of said bars.

4. The combination with a window having the usual upper sash, of a screen for such Window comprising a piece of flexible material, upper and lower bars to which such material is secured, and on which it may be wound, a bracket at each side adapted to support said bars, each bracket being shaped to embrace the end portion of both bars, and a swinging strip carried by each bracket and serving to lock the bars in position in said bracket.

5. The combination with a window having the usual frame, of a screen therefor formed of flexible material, a strip secured to the frame at each side, against which strip the free edges of the screen material are
